Control mode
Others
Conditions under which the software limit works
• Either at position control mode or full-closed control mode
SV.Pr02 = 0 : Position control
SV.Pr02 = 6 : Full-closed control
(1) operating Normal auto tuning
(2) After the last clearance of the position command input range (0 clearance), the movable range
of the motor is within 2147483647 for both CCW and CW direction.
(3) at Servo-ON
(2) when SV.Pr26 (Software limit setup) is other than 0.
Once the motor gets out of the (2) condition, the software limit protection will be invalidated
until the later mentioned "5) Condition under which the position command input range is
cleared" is satisfied. The position command input range will be 0-cleared when the motor gets
out of the conditions of (3) and (4).
• Time characteristics of Err16 (Overload protection)
• Software Limit Function
1)Outline
You can make an alarm stop of the motor with software limit protection (Error code No.34) when the
motor travels exceeding the movable range which is set up with SV.Pr26 (Software limit set up) against
the position command input range.
You can prevent the work from colliding to the machine end caused by motor oscillation.
2) Applicable range
This function works under the following conditions.
